GRAIN-DOOR FOR FREIGHT-CARS.

Specification of Letters Patent.

Patented March 31, 190s.

pplication led December 31, 1906. Serial No. 360,311.

To all whom fit may concern.' Be it known that I, JOHN B. SMILEY, acitizen of the United States, residing at South Omaha, in the county ofDouglas and State of Nebraska, have invented certain new and usefulImprovements in Grain- Doors for Freight-Cars, of which the followin isa specification.

his invention relates to grain doors for freight cars, having for itsobject the provision of a door which will form a close grain tight jointor union with the door posts or .jambs of the car to eHectually reventany eaka e of grain in transit; and) further to provi e the doorproper'with an auxiliary or relief door which 1s possessed of anoutwardly swinging movement to permit a suitable amount of grain toescape to thereby relieve in part the ressure against the door, enablingthe grain oor to be completely opened with ease and the ain to escape.

With the a ove andother objects in view my invention further consists inthe novel details of construction and combination of parts to be fullydescribed in the following s ecification and then pointed out in the caims.

Referring to the accompanying drawings Vforming a part of thisspecification, wherein like characters of reference denote similar partsthrou hout the several views z-Figure 1 is a side e evation of a freightcar showing my invention applied thereto, Fig. 2, is a longitudinalsection on line 2-2, of Fig. 1, Fi 3 is a vertical section on line 3-3of Fig. 1, gFig. 4, is a front view showing the grain door detached andin side elevation, Fig. 5 is a similar view of the rear of the graindoor, Fig. 6, is a vertical section on line 6-6 of Fig. 5, Fig. 7, is aerspective view of the W- shaped bars carrie by the grain door proper,Fig. 8, is a similar view of the angular hood secured to the door pro erat the top of the relief door opening, an Fig. 9, is a similar view ofthe angle iron which spans the lower side of the relief door opening.

1, denotes the door osts or jambs with which the joint is formedwith-the grain door pro er, 2.

e grain door proper is composed lof a plurality of horizontal pieces 3and verticalraces 4, suitably secured 'thereto the vertical edges ateach end of the door having the W-shaped bars 5, secured thereto so thatthe inner portions 6, of said bars 5, will abut the door posts 1, andthereby not only restrict the outward movement of the door 2, butfurther prevent such door being nailed to the posts 1. By inspection ofFig. 2 it will be observed that bars 5 closely engage the sides as wellas inner ends of door posts 1, thereby forming a close union between thetwo, which effectually prevents the escape of grain. It will further benoted that bars 5, embrace end braces 4 and thus not only add to thestrength of the door` at these points but also protect such bracesagainst wear and tear in removal and setting of the door from and intoclosed position. The door 2, is formed with a rectangular opening 7,which is adjacent the lower end thereof and extends through the lowerend, in which the relief door is received, the lower side of which y isspanned by angle iron 8, which thereby forms the fourth side of theopenin 7, the base of said angle iron being secure to the lower edgeofdoor 2, and the web of which engages the braces 4 and bars 5, the latterbeing cut away as indicated at 9, to receive angle irons 8. vThus angleiron 8 not only strengthens the ydoor 2, at its bottom and protects thesame in use, but it further by virtue of its upwardly'pro'ecting webrovides an abutment or stop or the. relief oor 10 which limits theoutward movement thereof. l

11 denotes an angular hood which is secured to the door 2, at the top ofthe relief opening thereof, this hood having an inner -f downwardlyextending portion 12, which engages the inner face of relief door 10,intermediate portion 13, and outer upwardly extending )ortion 14, whichis secured to braces 4 on eac side of the opening 7.

By reference to Figs. 1 and 2 it will be noted that braces 4, are cutaway at their Vlower portions so as to have their vertical edgesadjacent opening 7, disposed to the rear of the pieces 3, of door 2, tothereby form shoulders 15, against which relief door 10 may abut..Relief door 10, is formed of two members the outer one 16 of which isof less width than the inner one 17, which thereby provides for thereception of shoulders 15 and enables close engagement therewith, aswill be manifest from Fig. 2.

Each side of the relief door opening 7, is skirted by vertical bars 18which at their lower portions are secured to braces 4, as shown in Fig.5, and at their upper portions are offset as indicated at 19, to providespaces 20, in conjunction with the exposed faces of bars 4, as shownclearly in Fig. 6, the offset portions 19 being secured to verticalportion 14 of the anglar hood 11, thereby not only providing a rigidstructure, but further protecting braces 4 in use. Member 17 of therelief door receives on its outer face and at its upper edge a hinge bar21, which is rigidly secured thereto, the extremities of this hinge barbeing reduced as indicated at 22, Fig. 1, and being received in spaces20. It will thus be obvious that relief door 10 may be moved verticallyin spaces 20, and also swung outwardly at its lower end.

The member 17 of the relief door 10, is further strengthened by avertical bar of metal 23, secured thereto, the lower end ofl which isturned outwardly as at 24, to provide a hand hold in raising door 10,vertically, the upper end of bar 23 being engaged by a gravity tongue 24which is pivoted to member 14, of hood 11, and which frictionallyengages the upper edge of bar 23, and thereby normally prevents upwardmovement of relief door 10. By inspection of Fig. 3 of the drawings itwill be observed that the relief door 10, is capable of sufficientvertical movement to enable the same to clear the vertical portion ofangle iron 8, at the inception of` its outward swinging movement.

Each of bars 5, is provided with an opening 25, which receives hooks 26,on brackets stationarily supported at .the upper end of the car tosecure the grain door in position when out of use.

' The operation of the relief door is manifest from the precedingdescription. Tongue 24', bein moved free of engagement with bar 23, t erelief door is first raised, conveniently by use of hand grip 24,sufficiently to clear the lower edge thereof, of the upwardly projectingweb of'angle iron 8, when th'e same may be swung outwardly by virtue ofhinge bar 21.

Having thus fully described my invention, what I claim as new and desireto secureby Letters Patent, is:-
